TRACTION-WHEEL.

SPECIFICATION forming part of Letters Patent No. 358,532, dated March 1,1887.

Application filed January 18, 1887. I Serial No. 224,671. (No model.)

To all whom; it may concern:

Be it known that I, FREDERICK BEINDORF, a citizen of the United States,residing at Litchfield, in the county of Montgomery and State ofIllinois, have invented certain new and useful Improvements inTraction-WVheels; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to traction-engines which have the drive-wheelsprovided with adjustable spurs adapted to be projected beyond or drawnwithin the periphery of such wheels.

The improvement consists in the novel devices for adjusting such spursin or out at will, which will be more fully hereinafter set forth, andshown in the drawings, in which- Figure 1 is a plan view of the rearportion of a tractiolrengineprovided with my improvement; Fig. 2, a rearend view of one side of the engine and the device attached thereto. Fig.3 is a view, parts broken away, of one of the drive-wheels as seen fromthe inner side. Fig. 4 is a front view, parts broken away, of thedevices for setting and releasing the spuractuating lever. Fig. 5 is aperspective de' tail view of the setting-lever, showing by full linesthe position of the lever-projecting catch previous to its engagementwith the spur-actuating lever, and by dotted lines the position of saidcatch when in engagement with the spur-actuating lever. Fig. 6 is aperspective detail view of the releasing-lever, showing its operation byfull and dotted lines.

The object of the invention is to devise a simple, compact, andefficient means for projecting and withdrawing the spurs of atraction-wheel at will, and at the same time utilizing aportion of thepropelling power to effect such result.

The traction-engine comprises the body A, the axle B, and thedrive-wheels O, of ordinary and well known construction. The drivewheelsare provided at stated intervals with the adjustable spurs b, which arelocated in suitable openings formed through the rim of the wheel, andare'connected with the ring or sleeve D, mounted loosely upon the axleor hub of wheel, so as to turn thereon by the links b. Thespur-actuating lever E is connected at its inner end with the sleeve D,and its outer end passes through the keeper F, secured to the inner sideof the wheel, near its periphery. The keeper comprises two sides, d andd. The side d, which is adjacent to the body of the engine, has a notchat its rear end, forming the shoulder or stop (1", which engages withthe spur-actuating lever, and holds the same when moved back the fullextentof its travel by the lever-projecting catch G, pivotally connectedat its inner end with the settingleverH. The spur-actuating lever isheld under tension against the side (1 of the keeper F by its ownresiliency, or by the spring-arm e,or by thecombination of both suchforces. The spring-arm 0 may form an integral part of orbe separatedfrom and attached to the lever E, and its free end rests against theside (I, which forms a guide therefor in its movements.

The setting-lever H is pivoted between its ends to the bracket I,secured to the body A, and its outer end passes through the keeper J,while its inner end carries thelever-projecting catch G, composed of thetrip-arm g and the stay-bar or shoe 9. Thetrip-arm g is adapted to beprojected across the top of the keeper F within the path of thespur-actuating lever, and the shoe or stay-bar g, integral with andprojecting substantially at right angles to the trip-arm,is adapted totravel upon the outside of the keeper]? and hold the trip-arm inengagement with the spur-actuating lever till the latter reaches thelimit of its movement,which is when it is opposite to the notch in therear end of the sided of the keeper F. At this moment theforward portionof the shoe or stay-bar begins to leave the keeper, when it ceases tobear against its side, and the trip-arm turns back and rides over thespur-actuating lever. That portion of the shoe between its ends andadjacent to the keeper is removed to more readily permit thelever-projecting catch to disengage itself from the spur-actuatinglever. The spring 9 is interposed between the body A and theleverprojecting catch for holding thelatter in a normalposition Theouter end of theleverbears against the side of the slot 9' in thekeeper, and is held out of the Way or in an operative position by thestop j, projecting into said ,slot from its side. It is bifurcated,forming arms h and h, either or both of which may be elastic, so as tobe compressed for clearing the stop j when adjusting the lever from oneposition to another. The arms springing apart will engage with the stopand hold the lever in the adjusted position.

The releasing-lever K has its outer end, which passes through a secondslot, j in the keeper J similarly constructed to the outer end of thelever H,and held in either position by the stopj Thelever itselfispivotallysupported between its ends to the bracket 1, and its outerend is provided with the arm k,which terminates in the cam-head 70,which is adapted to be projected within the path of the spuractuatinglever and disengage the same from the shoulder dflwhen the weight of themachine upon the ends of the spurs, assisted by the spring a, willreturn the spur-actuating lever to its normal position and withdraw thespurs.

In practice, suppose it becomes necessary to project the spurs toprevent slipping of the wheel. The setting-lever is adjusted so that thelever-projecting catch lies in the path of the spur-actuatinglever,whichlever, engaging with said catch,is held till the wheel advances thedistance of the slot in the keeper. The catch is then disengaged fromthe spur-actuating lever,which is held against a retrograde movement bythe shoulder or stop d. T0 withdraw the spurs, the releasing-lever isadjusted to throw the cam-head within the path thereof, which cam-head,as the machine advances, engages with the spur-actuating lever anddisengages the same from the shoulder or stop (1 when the lever,returning to its normal position by the combined action of the springaand the weight upon the ends of the lowermost spurs, performs thedesired result.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

l. The combination,with the traction-Wheel, the adjustable spurs, andthe spur-actuating lever, of the setting-lever and the lever-projectingcatch, substantially as and for the purpose described.

2. The combination of the wheel, the adjustable spurs, the spur-actuatedlever, the keeper having a shoulder at one end, the setting-lever, andthe lever-projecting catch composed of a trip-arm and the stay-bar orshoe, substantially as described.

3. The combination of the wheel, the adjustable spurs, thespur-actuating lever, 'and the releasing-lever, substantially asand forthe purpose described.

4. The combination, with the wheel having adjustable spurs and thespur-actuating lever, of the releasing-lever and the arm projectinglaterally therefrom and terminating in a camhead, as and for the purposedescribed.

5. The combination of the wheel having adjustable spurs, thespur-actuating lever, the setting-lever, the lever-projecting catch, thereleasing-lever, the keeper-plate J, having two slots to receive theends of the settingand releasing levers, respectively, and the strapsprojecting into said slot, substantially as and for the purposedescribed.

In testimony whereof I affix my signature in presence of two witnesses.
